For some consumers that assessment is rooted in truth. People who don't regularly make long drives have unfounded range anxiety about BEVs but it's also true that for long, multi-day road trips the batteries and the infrastructure have not progressed to a level where finding an open, working charger and then still waiting around a couple hours is not a major inconvenience. Plus a lot of national parks are pretty remote with even fewer charging options and given the demographic of visitors more competition for spots.
Like akirby said, at least 5 years for solid state batteries and fast-charging infrastructure to make road trips convenient again. Imagine the nightmare Christmas/Thanksgiving traffic or hurricane evacuation would be right now if all of the cars on the road were a BEV.
For most people who have a place to plug in a vehicle at home, PHEVs today make the most sense from a purchase cost, fuel cost, maintenance cost and convenience perspective. But if you really, really want a BEV then get one and rent an ICE vehicle for national parks road trips.
